PLOW.

SPECIFICATION formingpart of Letters Patent No. 734,418, dated July 21,1903.

Application filed March 30. 1903. Serial No. 150,254. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN J ARRELL, a citizen of the United States,residing at Riverdale, in the county of Sumner and State of Kansas, haveinvented .a new and useful Plow, of which the following; is aspecification.

This invention relates to plows, and it has for its object to provide aplow suitable for operation in divers kinds of land, whether it be softand loamy or hard and dry soil.

Another obj eat of my invention is to provide a plowshare adapted to engage the groun d and to out beyond the land, thereby greatly relievingthe draft upon the plow caused by frictional engagement of the landsideof the plow with the land-furrow. A further object of my invention is toprovide a plowshare with means for supporting a separate cutter ofconcavo-convex shape, which said cutter shall be adaptedto extend beyondthe land and to turn the slice loosened thereby in the direction of themoldboard, thereby turning a wide slice and tending to center the draft.1

With these and other objects in view, all tending toward the productionof a device of this class, which shallpossess superior advantages inpoint of simplicity, durability, and general efficiency, my inventionconsists in the improved construction, arrangement, and combination ofparts which will be hereinafter fullydescribed,and particularly point edout in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a plowconstructed in accordance with the principles of my invention. Fig. 2 isa top plan viewof the same. Fig. 3 is a top plan view ofa plow-blade,illustrating a modified construction. Fig. 4; is a bottom plan view ofthe same. Fig. 5 is a sectional detail view taken on the line 5 5 inFig. 3. Fig. 6 is a perspective detail view of the cutter associatedwith the device illus- Fig. 7 is. a plan view illustrating amodification.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

In the embodiment of my invention I employ a plowshare 1 and moldboard2, which may be constructed either separately or integrally and which,as shown in Figs. 1 and 2, are supported upon a landside 3 and brackets4, suitably extending from said landside. Additional brackets are to beprovided for the Y attachment of the plow to suitable supporting means,which, however, have not been shown in the drawings.

In the general construction of the moldboard of the device no novelty isclaimed; but the share is provided with a lateral extension 5, which isconcavo-convex in cross-section and'which is curved upwardly andoutwardly in the direction of the land, the outer edge of said extension5 being sharpened to form a cutting edge 6. In Figs. 1 and 2 of thedrawings this extension and cutting edge have been shown as being formedintegral with the share 1; but in Figs. 3, l, 5, and 6a modification isillustrated, which consists in providing the share with a lateralextension 7 in the direction of the land and securing upon the underside of said extension a reinforcingplate 8, which is welded to orotherwise permanently connected with the under side of the point of theshare. Therear end of said reinforcing-plate is not connected with theshare, between which andsaidreinforcingplateis, in this case, inserted acutting-blade 9, which may be described as being approximatelyconcavo-convex in cross-section, so that when inserted in positionbetween the edge 'of the plowshare and the reinforcingplate 8 the saidcutting-blade shall be curved upwardly, so as to engage the'land inprecisely the same manner as 'the upwardlycurved projection 5 of theform of the device illustrated in Figs. 1 and 2. This cutter 9 is Vclamped detachablybetween the projecting edge of the plowshare and thereinforcingplate 8 by means of a bolt 10 or other suitable means whichwill admit of the said out ter being detachedwhen desired for thepurpose of sharpening the same or of'replacing it with a new one whennecessary. It will be observed that the outer edge ofthereinforcing-plate 8 is beveled to a sharp edge 11, which is flush withthe under side of the cutter 9, so that when the parts are assembled foroperation there shall be but slight frictional resistance to theprogress of the device through the soil.

It will be observed that by the use of either device thus far describedthere will be a strong tendency toward the centering of the draft, owingto the lateral extension of the share in the direction of the land, thedraft being obviously applied in the usual manner in the line of thelandside of the plow. In order to increase this tendency to thecentering of the draft, I may sometimes avail myself of the modifiedconstruction illustrated in Fig. 7, where it will be seen that thefurrow end of the share is removed, so that the furrow edge 12 of theshare shall be in longitudinal alinement with the furrow edge 14 of themoldboard. \V hen this construction of the share is employed, it isevident that not only is draft upon the plow greatly relieved, but atthe same time the furrow will be cut slantingly, such as it would becutby means of a rotary disk, with this exception, however, that thebottom of the furrow will be cut flat by that portion 15 of the edge ofthe share which is disposed between the trimmed edge 11 and the point.This feature is considered of considerable importance, inasmuch as amuch superior surface is provided for the draftanimals to travel uponthan when rotary disks are used, while the advantages resulting from theuse of rotary disks, mainly consisting inso turning the soil as to burythe hard and dry crusts and leave the soft pulverized portion of thesoil exposed, leaving the ground in a superior condition for subsequentcultivation, are retained.

It is obvious that several of the forms .of my invention (illustrated inthe drawings and hereinbefore described) may be attached to ordinarybeams and standards and employed as walking-plows or that they may be0011- neeted with suitably constructed sulkyframes as riding-plows It isalso obvious that a plurality of my improved plows may be used inconnection with each other to form a gang composed of any desired numberof units. I desire it, furthern'iore, to be understood that my improvedplow is Well adapted to be successfully used in connection with rotarycolters, which are at the present time frequently and successfully usedin'connece tion with plows of various constructions.

I have in the foregoing described certain preferred forms ofconstruction of my improved plow; but I desire it to be understood thatIdo not limit myself with regard to structural details or to the size,form, and relative proportions of the members of the device, but reserveto myself the right to any changes, alterations, and modifications whichmay be resorted to within the scope of my invention without departingfrom the spirit or sacrificing the utility of the same.

Having thus described my invention, I claim- 1. In a plow, a sharehaving an extension forming a cutter curved upwardly and outwardly inthe direction of. the land, with its concave side uppermost.

2. I11 a plow, a share having an extension projecting laterally in thedirection of the land, a reinforcing-plate upon the underside of saidextension, and a cutter clamped between the latter and thereinforcing-plate, said cutter being curved upwardly and outwardly inthe direction of the land, forming a longitudinal concavity in its upperside.

In a plow, a share having an extension projecting laterally in thedirection of the land, a reinforcing-plate connected permanently withthe under side of the point of said extension, a cutter clamped betweensaid extension and the reinforcing'plate, and a connecting-bolt.

4. In a plow, a share having a lateral extension projecting in thedirection of the land, a reinforeing'plate permanently secured to theunder side of the point of said extension and having a beveled outeredge, a cutter fitted between the extension of the shareand thereinforcing-plate, said cutter having an upwardly and outwardly curvedcutting edge, and suitable clamping and connecting means. In testimonythat I claim the foregoing as my own I have hereto affixed my signaturein the presence of two witnesses.
